The gas pressure- At this time, the test well head 300 and the BOP equipment 200 may be placed in a separate pressure vessel 100, as shown in FIGS. 1 and 2.

The pressure vessel 100 is formed in the form of a container in which a test chamber C is formed and a liquid L is stored in the test chamber C so that the BOP equipment 200 can be locked. The pressure vessel 100 may be formed in the form of a container having various shapes in which a test chamber C is formed. It is preferable that the pressure vessel 100 is formed in a cylindrical shape in consideration of the supporting strength against the internal pressure of the pressure vessel 100 . In addition, the pressure vessel 100 may be configured in such a manner that it is connected to a negative electrode power source for corrosion prevention.

1, the pressure vessel 100 includes a container body 110 having a part of an upper surface thereof opened so as to form a test chamber C in an inner space thereof, And can be separately formed by the container cover 120 to be coupled. The liquid L can be stored in the test chamber C of the container body 110 with the container cover 120 opened through such a structure and the liquid L can be stored in the test chamber C of the BOP equipment 200 may be charged into the test chamber C so as to be immersed in the liquid L.

The pressure vessel 100 may be disposed on the shore or disposed on the seabed. When the vessel is disposed on the shore, a liquid may be supplied and stored in the pressure vessel 100 by using a separate pump or the like, The seawater can be stored in the pressure vessel 100 in such a manner that the vessel cover 120 is simply opened.

On the other hand, when the pressure vessel 100 is disposed on the shore, the BOP equipment 200 can be introduced into the pressure vessel 100 by using a separate crane (not shown) 220 may be connected to the BOP equipment 200.

According to such a configuration, since the BOP equipment 200 is tested in a state of being immersed in the liquid in the test chamber C, the test operation can be performed in water just as it is installed in the seabed, so that more accurate test results can be obtained. Further, although not shown, a separate external pressure supply unit (not shown) may be connected to the container body 110 to supply pressure to the test chamber C. The external pressure test may also be performed on the BOP equipment 200 through the supply of external pressure through the external pressure supply unit.

The test well head 300 may be fixedly mounted within the pressure vessel 100 such that the BOP equipment 200 is latched. This test wellhead 300 is the same as the wellhead coupled to the top of the subsea well and is fixedly mounted within the pressure vessel 100 for testing on the BOP equipment 200 in one embodiment of the present invention. At this time, the BOP equipment 200 and the test well head 300 are coupled to each other so that the internal spaces are communicated with each other in a state where they are latched to each other.

The pressure flow tube 410 is coupled to the test well head 300 such that an internal pressure is provided to the BOP equipment 200 through the test well head 300. The upper end of the pressure flow tube 410 is connected to the test well head 300, And the lower end of the pressure flow pipe 410 is coupled to the pressure-resistant supply unit 400 so that high-pressure liquid can be supplied. Also, a gas supply unit 500 is also connected to the pressure flow pipe 410 so that high-pressure gas can be supplied to the test well head 300 and the BOP equipment 200.

According to this configuration, high pressure liquid and high pressure gas are supplied to the BOP equipment 200 through the pressure flow pipe 410 by the internal pressure supply unit 400 and the gas supply unit 500. Therefore, unlike the prior art in which the internal pressure is generated by simply supplying the high-pressure liquid, the high-pressure gas can be supplied to the BOP equipment together with the high-pressure liquid, whereby the gas kick situation can be reproduced, You can perform a test operation. In addition, this allows more accurate testing of BOP equipment and improves the reliability of test results.

Meanwhile, the pressure-resistant supply unit 400 according to the embodiment of the present invention is configured to supply the mud liquid, and the mud liquid supplied through the pressure-flow pipe 410 from the pressure-supply unit 400 is supplied to the test well (300) and the BOP equipment (200), and then circulated along another circulating pipe (P). In this case, the riser 220 is connected to the BOP equipment 200, and the mud liquid passing through the BOP equipment 200 is supplied to the mud circulation line of the riser 220, for example, Is supplied to the circulation pipe (P) through the kill line (221).

Further, since the mud liquid is circulated to a high-temperature state of approximately 300 to 400 ° F in an actual seabed drilling operation, the circulating mud liquid according to an embodiment of the present invention is also preferably heated to a high-temperature state similar to the actual environment . A separate heating device 620 may be provided on the circulation pipe P connecting the storage tank 610 and the internal pressure supply unit 400 so as to heat the mud liquid delivered to the internal pressure supply unit 400 have.

The separated mud liquid again passes through the storage tank 610 and the heating unit 620 and is transferred to the internal pressure supply unit 400 and then returned to the BOP equipment 200 Circulated.

FIG. 2 is a view schematically showing a configuration of a gas kick test apparatus of a BOP apparatus according to another embodiment of the present invention, and FIGS. 3 to 8 are diagrams of a gas kick test apparatus of the BOP apparatus shown in FIG. A gas layer formation process and a gas kick generation process.

2, the gas kick test apparatus of the BOP equipment according to another embodiment of the present invention may be configured such that the gas layer 700 is formed in the middle portion of the pressure flow pipe 410. [ The gas layer 700 may be formed using an internal pressure supply unit 400 and a gas supply unit 500 that are connected to the pressure flow pipe 410. The gas layer 700 thus formed may be formed in the internal pressure supply unit 400, So that the gas layer 700 is exploded and supplied to the BOP equipment 200.

As shown in FIG. 2, the gas layer 700 includes a first plug 710 and a second plug 610. The first plug 710 and the second plug 710 are spaced apart from each other along the length direction of the pressure flow pipe 410 to block the flow path of the pressure- May be formed in the space between the second plugs 720. At this time, the first plug 710 and the second plug 720 block the internal flow path of the pressure flow pipe 410 so that the volume of the gas layer 700 can be adjusted, And can be formed movably. The rupture disk 711, which is broken as the pressure of the gas layer 700 is pressed to a predetermined pressure or more, may be mounted on the first plug 710.

According to this structure, when the high pressure liquid is supplied through the internal pressure supply unit 400 in the state where the gas layer 700 is formed in the middle section of the pressure flow pipe 410 and pressure is applied to the pressure flow pipe 410, The first plug 710 and the second plug 720 move by the internal pressure, the volume of the gas layer 700 decreases, and the internal pressure of the gas layer 700 rises. As the process progresses, the rupture disk 711 of the first plug 710 is broken due to an increase in internal pressure of the gas layer 700. At the same time, the gas of the gas layer 700 is tested along the pressure flow pipe 410 And is supplied into the well head 300 and the BOP equipment 200.

Since the gas supplied to the BOP equipment 200 is instantaneously supplied to the BOP equipment 200 through the above process, a high-pressure shock may be applied to the BOP equipment 200, Since the condition is very similar to the gas kick situation occurring in the oil well, a more accurate pressure resistance test for the BOP equipment 200 can be performed.

At this time, the internal pressure test is performed in the state where the test pipe 202 is inserted into the BOP equipment 200. In this case, the inside of the BOP equipment 200, which is the Ramp unit 201 mounted on the BOP equipment 200, The gas of the gas layer 700 may be configured to be supplied to the BOP equipment 200 while operating to close the holes so that a shock due to the gas pressure may be applied to the device such as the ram device 201 and the annular have. Of course, alternatively, the gas may be supplied to the BOP equipment 200 after the gas in the gas layer 700 is supplied, and then the test may be performed in such a manner as to operate the apparatus such as the ram unit 201 and the annulus.

Next, a process of forming the gas layer 700 in the pressure flow pipe 410 with reference to FIGS. 3 to 8 will be described. First, as shown in FIG. 3, the pressure supply unit 400 is operated, 410). ≪ / RTI > At this time, the pressure-resistant supply unit 400 may be configured to pump the liquid M from the separate liquid storage tank 401. Then, as shown in FIG. 4, the first plug 710 is inserted into the pressure-flow pipe 410, and the high-pressure gas is supplied through the gas supply unit 500. At this time, the gas supply unit 500 may be configured to compressively supply the gas from the separate gas storage tank 501. When the high-pressure gas is continuously supplied as described above, the first plug 710 moves along the pressure-flow pipe 410 as shown in FIG. 6, the second plug 720 is inserted into the pressure-flow pipe 410, and the high-pressure liquid M is supplied through the pressure-supply unit 400. [ 7, the second plug 720 is moved along the pressure-flow pipe 410, and the first plug 710 and the second plug 720 A high-pressure gas layer 700 is formed.

In this state, when the high-pressure liquid M is continuously supplied to the pressure-flow pipe 410 through the pressure-supply unit 400, the second plug 720 moves and the pressure of the gas layer 700 gradually increases, 8, the rupture disk 711 of the first plug 710 is broken and the high pressure gas existing in the gas layer 700 is momentarily tested along the pressure flow pipe 410 And is supplied to the well head 300 and the BOP equipment 200.

On the other hand, the liquid is an incompressible fluid, the change of the volume with the pressure change is relatively small, and the gas is the compressible fluid, and the volume change with the pressure change is relatively large. 5, in order to move the position of the first plug 710 through the supply of the high-pressure gas by the gas supply unit 500, the inside of the pressure-flow pipe 410 is connected to one side of the pressure- A discharge port 411 for discharging the liquid is formed and an opening and closing valve 412 for opening and closing the discharge port 411 can be mounted on the discharge port 411. The position of the first plug 710 and the gas layer 700 can be adjusted through the discharge of the liquid M through the discharge port 411. That is, since the liquid is an incompressible fluid, the liquid M is discharged through the discharge port 411 during the supply of gas or liquid through the gas supply unit 500 and the pressure supply unit 400, The position of the first plug 710 and the gas layer 700 can be adjusted.

The pressurizing of the pressure-flow pipe 410 causes the gas layer 700 to explode and be supplied to the BOP equipment 200. [

3 to 8, first, the liquid M is supplied into the pressure-flow pipe 410 through the pressure-supply unit 400 (S31), and the pressure fluid pipe 410 is filled with the liquid M, The first plug 710 and the second plug 720 are inserted into the pressure flow pipe 410 while the liquid M is stored in the space between the first plug 710 and the second plug 720, And a method S33 for supplying and supplying the liquid M to the pressure flow pipe 410 through the pressure supply unit 400 in this state (S32).
